Cisco MGX 8850/B Advanced ATM Multiservice Switch
®
®
The Cisco MGX 8850/B Advanced ATM Multiservice Switch is a carrier-class solution
for data and voice networks. It supports a full suite of ATM/FR Layer 2 multiservices,
Packet Voice, and IP/Multiprotocol Label Switching (MPLS) for service provider
applications.
Product Overview
The Cisco MGX 8850/B Advanced ATM Multiservice Switch (Figure 1) inherits the proven
architecture and reliability of the Cisco MGX 8850 to deliver mission-critical networking services. It
offers a choice of switching options: 1.2Gbps for low-speed aggregation or 45Gbps for highbandwidth applications. The physical interfaces supported range from T1/E1 to OC-48/STM-16,
Ethernet to Gigabit Ethernet, and OC-12 Packet over SONET. The Cisco MGX 8850/B’s multiple
simultaneous control planes provide flexibility and scalability while providing standard
Asynchronous Transfer Mode (ATM) with advanced traffic management capability, MPLS for IP
services, frame relay for traditional Layer 2 data services, circuit emulation, and Packet Voice
services. The Cisco MGX 8850/B is an upgraded version of the Cisco MGX 8850 and utilizes
specially designed redundancy connectors (RCONs) to support 1:N redundancy without the use of
the Cisco MGX Service Resource Module.

Applications
●
Multiservice switching: Deliver revenue-generating services at the edge of the service
provider network. Layer 2 services such as ATM, Frame Relay, Circuit Emulation, Packet
Voice, and IP/MPLS services can be offered in a single platform to reduce capital and
operational expenses. The variety of narrowband and broadband interfaces ranging from
T1/E1 to OC48/STM-16 enables service providers to offer multiple services for voice, data,
and video, in the same network infrastructure.
●
Media gateway for voice over IP (VoIP) and voice over ATM (VoATM): Deliver revenuegenerating voice transport applications and services by supporting industry-standard VoIP
and VoATM. The advanced capabilities of the Cisco MGX 8850/B allow for bandwidthefficient transport of voice over a multiservice backbone network. The voice modules
(VISM-PR and VXSM) of the Cisco MGX 8850/B, together with a compatible softswitch,
support a number of call control protocols (such as Trunking Gateway Control Protocol
[TGCP], Media Gateway Control Protocol [MGCP], H.323, and Session Initiation Protocol
[SIP]) to provide a variety of Packet Voice applications.
●
Aggregation and backhaul for mobile networks: The Cisco IP Radio Access Network (RAN)
Transport solution allows mobile operators to optimize the critical transport segment for
backhauling traffic using IP/MPLS from cell sites. This significantly reduces backhaul costs
for 2G and 3G services and improves cell site maintenance.
●
Universal Mobile Telecommunications Systems (UMTS): The Cisco MGX 8850/B supports
a wide range of network interfaces between T3/E3 and OC-48/STM-16 for aggregation and
switching and is ideal for UMTS RAN aggregation applications, where the Cisco MGX can
be used to aggregate multiple T1 or E1 links from cell sites for transport over an optical
backhaul network.
Primary Features and Benefits
●
1.2-Gbps and 45-Gbps nonblocking switching capacity: The Cisco MGX 8850/B provides
flexibility for broadband multimedia applications that demand high switching throughput.
The PXM45/C processor module provides a 45-Gbps switching fabric and management
control. Alternatively, the PXM-1E module offers savings by combining both the 1.2-Gbps
switching function, management control, and multiple network interfaces in one module.
The PXM1 module is also supported. All PXM modules support redundancy configuration
for high availability.
●
Flexible service mix: Service modules may be installed with interfaces ranging from NxDS0
to OC-12/STM-4 to meet individual business needs. This includes the ATM Switching
Service Module (AXSM-XG), with its superior traffic management capability for broadband
networking. The full-height slots can be used with half-height modules to optimize the
chassis for low-speed interface density. Multiprotocol service modules (MPSMs) provide
support for ATM, FR, and CES in the same module, allowing for maximum deployment
®
flexibility. The route processor modules (RPMs) run Cisco IOS Software and provide full
support for IP and MPLS networking. The Voice Interworking Service Module (VISM-PR)
provides support for VoIP and VoATM functionality, and the Voice Service Switch Module
(VXSM) provides high-capacity VoIP services.

●
High-availability features: The Cisco MGX 8850/B can be optionally configured with 1:1
redundancy for all common components (switch fabrics, control processors, clock
interfaces, and power supplies). The switching capacity remains unaffected by the
redundancy configuration.
●
Service reliability: All Cisco MGX products support the use of 1+1 Automatic Protection
Switching (APS) for optical interface modules; 1:1 redundancy for T1/E1, T3/E3, and optical
modules; and 1:N redundancy for T1/E1 modules; all of which are crucial for maintaining
service uptime.
●
Common element manager: For the ease of end-to-end operation and operational cost
saving, all Cisco MGX products can be managed by the same Cisco WAN Manager. The
Cisco Wan Manager is a proven management tool; it has a work-flow simplifying graphical
user interface (for day-to-day maintenance and task monitoring) and offers a highly
scalable network discovery capability, high-performance flow-through provisioning
interfaces, and distributed statistics collection capability.
